I have a Microsoft LX 3000 headset that normally works fine. But today it has started randomly failing, what i mean is it works for a few minutes on a fresh boot and then stops(and it disappears from pavucontrol) unplugging and re-plugging sometimes makes it work again for a minute or less, sometimes it doesn’t help at all

Running Ubuntu 12.04 64bit with KDE 4.12

and i did a software upgrade earlier today, before the problems started(it was probably before they started)

Any ideas please?
